NEKOOSA, WI (WTAQ) - An 18-year-old Nekoosa High School student faces a possible criminal charge, after an incident that sent students home early on Monday.

Police have asked the Wood County district attorney for a disorderly conduct charge – but nothing was filed as of late Tuesday.

Authorities said the teen wrote on a social media site that he had a gun at the school. Once school officials caught wind of it, police arrested the teen – and he denied bringing any weapons to school.

The building and grounds were searched on Monday afternoon, and no weapons were found.

Normal school activities resumed Monday evening.
